    M5030su will not run/revv up after warming up.

    My first son is now 18 months old so you do the math. :D It has been just the same. We just haven't used it very much. Now that it's hot outside, the problem is more evident though. I will someday get enough time to take it apart or sell it. Ha ha Will update you guys in another couple of...

    M5030su will not run/revv up after warming up.

    Due to the way that life has unfolded over the past year or so, we actually never got a chance to take the tractor apart. I had to use a tractor yesterday to dig up a busted water line. It was so hot outside… The tractor did the same old thing and after it got hot, it would barely idle and...

    M5030su will not run/revv up after warming up.

    Okay thanks it makes more sense looking at it now, knowing that what I'm looking for is not really there. ;) Thank you for showing me which part is which. I have squeezed and pinched the rubber lines while the issue is occurring and didn't notice any difference, but that really doesn't say...

    M5030su will not run/revv up after warming up.

    Here are some photos of the pump area that I took today. I must be honest and tell you that I do not know exactly what I'm looking at. Can you point me to the location of the throttle plate or compensator? ...and by the way thank you for the help thus far.

    M5030su will not run/revv up after warming up.

    Now that I have looked over the parts diagram a little more and have thought about what is happening and what that thermostat is doing in the throttle plate, I think that you are right Wolfman. I am very tempted to order this thermostat right now. Would it be possible to ask if there is...

    M5030su will not run/revv up after warming up.

    Unfortunately only one of those photos/attachments works for me. I can see the throttle plate with compensator but that's it. I do see 130 in the diagram though, and if that is a thermostat, than that definitely seems to make some sort of sense. The engine does not turn off with the key. You...

    M5030su will not run/revv up after warming up.

    Shaun, Yes, this only happens after at least 45 minutes, but usually longer. I would say that the average time to re-create the issue is 45 minutes-1 hour of normal usage. Wolfman, The serial number of the machine is 560801. Model number 195. The engine model says S-2802-DI-A If I am...

    M5030su will not run/revv up after warming up.

    I removed the fuel cap while the issue was occurring and try restarting, etc. Venting the fuel tank seemed to have no effect on the issue. One of the hydraulic hoses for the front loader busted yesterday, so it may be a couple of days before I'm able to test again. The worst part of it all is...

    M5030su will not run/revv up after warming up.

    Thank you for the quick reply. Your response jogged my memory. We did take the tractor to the local Kubota dealer and described the issue to him. He replaced the fuel filter. He told us that he use it for a while and could not get it to re-create the problem again (I know that he just did not...

    M5030su will not run/revv up after warming up.

    My grandfather bought a M5030su at an Ag auction last winter. The tractor was sold advertised as in good running condition. From the exterior, it looked to have been worked pretty hard, but is in solid condition. We have had plenty of issues with small things like hydraulic lines to the...
